  1. tammy tonner-avatar

    I discovered the quick access for take pictures by shaken the phone but it only worked once.. but no ads that makes me happy & the boost seems to help.. I ended up deleting it because it muted all of my notifications and I couldn't figure out how to stop it was in get in my game notifications or my text messaging so it's gone now..

  2. Misty mcdonald-avatar

    This app does exactly as described. One button cleans phone up and no ads! Excellent job developers admins everyone involved in making this the easiest end user app experience I've had yet. Keep up the good work and thank you.

  3. Steven Minish-avatar

    Thanks, works great! After trying like a dozen apps on this old generic andriod 3g tablet that kept dragging and crashing even tho I cleared the data catch like a half dozen times a day, finally its working ok now. Good there's no ads either

  4. How_To_ Pro AsD-avatar

    Nice Booster app , now i can play games without lag and i foundvthis very usefull and my phone (HTC One m7) becomes fantastic and this app cools down the temp ,thank you very much and you deserve more than 5 stars.

  5. Pram gupta Gupta-avatar

    Pram gupta Gupta


    It's a fine app. But it keeps showing you that you have cleaned up your junk files and the phone's boosted, but that means we have no junk files at all! There is something wrong with the app, I want the publishers to correct this default. I have deleted this app because of this, so correct this issue. It is a battery draining app as well as user tracking application. Also I want to give it 1 star but now it is not changing.

  6. A Google user-avatar

    EDIT: Latest update seems to fix the issues im having. Original Review (3 stars): crashes alot, and latest update makes it where it crashes all the time, even when not being used and crashes in the background. overall, when it does finally load, i can tell a difference, but please fix the new update, it crashes all the time now, i cant even open the app

  7. Joseph Russell-avatar

    Nice and very easy to use. Free and I think I am getting much better phone service for web. Thanks speed booster.

  8. Jessie-avatar

    This app is literally the only reason I'm able to use my buggy J7 anymore. There's an option to automatically & silently run the booster, clear cache, & close any background apps or tasks (of your choosing) EVERY time the screen turns off. My phone would be completely useless without it. Devs: A high-five and a hearty "Huzzah!" for each of you. Thanks for saving my phone and my sanity!

  9. Sp!ke Brannigan-avatar

    Sp!ke Brannigan


    This is gonna sound like a REALLY stupid question, but...do you have any plans for an app devoted exclusively to the care, maintenance, and extension of the life of the batteries on your customers' devices, including (but not limited to) keeping track of the amount of time remaining during a recharge before the battery is at 100% again (and even showing on the toolbar how much juice is left in the battery when it's in use), hibernating autostarting apps, etc.?

  10. JC R-avatar

    Easy and simple interface. It really boost the RAM. The only issue is that the 'Ignore List' can't be set up... too bad. That feature is available in other apps I've tried before. There's one more issue... it draws battery charge too when not in use, as other apps aswell.

  11. Austin Smith-avatar

    Been trying to find the best device maintenance app without any ads!! And this one is true, works perfect SO FAR!! IF ANY CHANGES COME I WILL CHANGE MY RATING AND UPDATE!! So this comment and rating is actually pending...

  12. Zbird Tbird-avatar

    Quick easy simple fast... No graphs or percentages ... I guess it's working. Google Files also says it cleans junk files and I can't see any difference they have on each other's result reports or anything. This is not new to me. If you have two junk cleaners and you can't see any effect on either of them by either of them. How can you trust any of the calculations or readouts of either "service" I run them both or just one. Hey support. Can I get an explanation?

  13. Christopher Eicholzer-avatar

    Christopher Eicholzer


    This app boost my phone a little bit at first ... But then I used it for a few days now and my phone I could definitely see and notice BIG difference. Download it and give it a shot you won't regret it.😀😀😀💚💚💚💚💚💚💚💚💚💯💪🔥🔥🔥🔥🔥🔥.

  14. Richard Miller-avatar

    This app makes no notable difference to the performance of my device other than making it a bit slower. I can "clean" or "boost performance" every 5 minutes and it still has data and junk to clean. Funny thing is, I can't for the life of me see or notice any increase in the actual performance of my device. I don't understand why these apps even exist. They do absolutely nothing besides bog your phone down, spit adds, and constantly try get you to purchase their premium b.s.

  15. Kartunhub Channel-avatar

    This app usually be my daily use to clean up the junk on my phone. By the way, I think it's useful apps sometimes it's might be not. Hopely that this app could be more improvement next time.

  16. Renee Whitley-avatar

    This app is great! It fixed any kind of lag or RAM problem with one tap! The only thing that could use some work is the new features it says you can do after boosting your phone. It says you can access our camera by shaking your phone but it doesnt work. Other than that this app is perfect!

  17. F Zaza-avatar

    #1 The app only lets you know what was slowing your phone BEFORE cleaning. But 95% of the time, when my phone is slow, I just select "clean junk" before worrying what exactly is slowing the phone. After cleaning junk, it cannot check what it has cleaned. It should allow you to also check immediately after cleaning. #2 It should allow you access to the app when your phone slows so you dont rven need to exit another app. #3 It should look a bit less like a kids game and a bit more serious.

  18. No One-avatar

    Awesome app, so much, that it's one of the first apps i installed on any new device and tell anyone i hear mentioning that their phone is slowing down. highly recommended

  19. Mario Scooby-avatar

    Complete fraudulent app. Instead of boosting, it does the job of cleaning and deleted my files like extracted apps which I use for studying as app developer and photos without telling me or taking my consent. Why do you promote as ram booster when you have to do the job of clean master? Horrible experience.

  20. Robert James-avatar

    I just want to say i've tried many boosters and this one i like. Its fast, does its job and no interuptions. Well done .

  21. Bob P Wilson-avatar

    SHOCKED! 10 STARS 🎇🎇🎇🎇🎇🎇🎇🎇🎇🎇 My fancy Samsung S8-Plus has been slow running and sluggish, for months now. I've been considering completing a full factory reset. While installing another app I ran across this booster app, read the user reviews and installed the app. I thought this app would be just another booster app that you ran and saw few results, but I was wrong. The first time I ran this cleanup app, it actually processed my device files for a long while... However, when it finished, this app found enormous amounts of junk data and files that neither my Avast cleaning app, nor my Samsung maintenance internal system cleanup app, has never found! Once the app completed the initial cleanup, I rebooted my S8-Plus, and my device is back to running like brand new!!! Yes, this free app works so much better than my fancy, paid, Avast mobile cleanup app and my built in Samsung Galaxy S8+ device cleaning app!! I highly recommend the use of this app for slow, sluggish smartphones. I've used many system cleanup apps, but this app has out performed every fancy app on Google Play Store! Thank You Developers!

  22. Michelle Post-avatar

    I have had this app in my android since June 2019, and it's November now.The app really works...and gets rid of cache.I have also noticed more memory created.I have used many of these type apps over the years, they gobbled up masses of MB, and never showed any proof of working. This app uses little MB, and the program never bothers my photos in the Gallery app!!! I have never even encountered an ad from it. I will keep this app, & reccomend this app to anyone!!

  23. Bobbie Grimes-avatar

    Simple. Easy to use. Frees up resources & tells you when something keeps restarting so you can stop it.

  24. Maria Graciela Otoya Diehn-avatar

    Maria Graciela Otoya Diehn


    This app has very effectively improved the performance of my old Android. And it is free! Thanks!

  25. CosyHamster-avatar

    Amazing first tap on the app and it cleaned all my junk apk files! I am so happy with the app. And it's booster is perfect for my laggy device! But can you make a feature where it will delete all my .mcworld files so when I go in settings and add it so when it cleans it will also clean those files too! Also it can be moved on my SD card so I can save all the storage space I need! Recommend downloading on your very slow phone!!! 👍

  26. anita pulani-avatar

    Excellent clean up app !!! Just live it . I havw one problem though. I have to manually do system scans . Is there a way to automatically refresh ?

  27. Joseph Williams-avatar

    Joseph Williams


    One of my All - time favorite cleaning apps it's simple & effective cleans your Phone quick & you can still keep all your videos " Pics without having the fear of accidentlly deleting something very important like the other cleaning apps Good Job !!! you just need to fix the hibernation feature other than that it's Awesome God bless the creators ! thank you...

  28. Jeff Moreland-avatar

    I have been quite satisfied with how my phones performance overall has been improved by the installation and subsequent running of this application. Thank you for designing a "cleaner/booster that simply does just that. Well done! "Simplify to Amplify" you've nailed it! Respectfully, Mr. Jeffery G. Moreland

  29. Kay Cee-avatar

    Used to be better. When I first downloaded it, there was an option to hibernate apps that were idly consuming processing power. Then there was an update, and now that option is gone. I find that Booster no longer "boosts" my phone to the same degree without that hibernation option. Went from great to mediocre.

  30. Paul Fakudze-avatar

    Very good application, works efficiently. I love it. Makes my phone run so smoothly.

  31. Mike Smith-avatar

    Doesn't do much. I checked before and after on ram truth and there was only a slight change. Other apps have had more of an effect.

  32. Denise Shumaker-avatar

    Denise Shumaker


    I absolutely love it!!No ads. 90% of the other cleaners add to why your phone needs to be cleaned in the first place! They are so crappy! This one is simple basic and you have total control over when your phone needs to be cleaned highly recommend it!👍Thanks.

  33. plockstock-avatar

    I think its the best speed booster app in the market plus its ad free so you wouldn't have to deal with ads. My only problem from is that sometimes it crashes when you open the app, well its just a minor problem since when you open the app 2nd time the app won't crash. Anyways thanks dev team! :)

  34. rupam kumari-avatar

    My smartphone is always hang. When install speed booster my phone is really excellent. Its magic app. Thanks spped booster.

  35. Matthew's Gunners-avatar

    Matthew's Gunners


    This really works well with a decent prossesor booster in tow. I am running a galaxy note 5. Not the fastest phone on the market anymore. But will now play just about anything on the playstore. As i was saying a most impressive peice of software. Do too the now established fact that this indeed works quite well.

  36. JRs Tablet-avatar

    Application great until update then crashed couldn't send debug results but had to restart android system then reinstall most applications that had been loaded on the tablet (including Speed Booster. That is a pain but each app affected was shown as not found on home screen. Hope you can fix this; please, ASAP.

  37. Kerrie Connelly-avatar

    Kerrie Connelly


    Fantastic.It totally fixed a failing battery that needed to be charged 3 times a day. Not anymore. No ads.👍

  38. Vorxet-avatar

    Why does it need my location. A simple app that cleans up junk files and memory should not need my location. Also a cooler cpu dowles not make it faster, unless it clears it's catch. But still, it's not making it run faster. It dosnt have ads though, I'll give it that.

  39. MW-avatar

    No change in performance. I got this because: 1) Outlook now takes 15 secs to load my emails, and 2) my phone gets very hot if it's on more than 10 mins. Speed Booster didn't find much junk to clean out, told me the CPU was running normally, and didn't solve the Outlook lag. [Samsung Galaxy S7 edge.]

  40. Alan High-avatar

    Continuously stops and malfunctions. Very odd. When it "crashes", it requests that you send a report. FYI, this app was developed in China, and may be a data miner. I deleted it. An ad-free app that's free? Hmm........

  41. Nic Alexander-avatar

    I've used almost every single Ram/Junk cleaner app on the playstore and this is by far the best. It does exactly what you need it to at the click of a button without annoying ads popping up every 2 seconds! Love this utility and highly recommend it!

  42. Rob Postle-avatar

    Decent app, Doesn't spam you with ads on lock screen and really like that. The shake phone for camera option may seem like a smart idea but it will shake in your pocket, turning you phone on sometimes pocket dialing people. I had to turn that option off.

  43. Shivani Mishra-avatar

    the best booster app, I had ever used. The best thing about this is all the unwanted cache and junk is removed but there is no harm to any type of data. Congratulation to the developer(s),I liked this app very much.

  44. TroNGeniX-avatar

    the app is too harsh at first lunching, insteaf of boosting RAM first. it considerd my apps as junk . wiped all my apks in my storage without giving me notice or option to allow me choose if i want them to be junk files . now i have to re-download a whole lot of apps equivalent to 9Gb. its a nice app though. it does its task.

  45. Dickinson DigiGal Gaming-avatar

    Dickinson DigiGal Gaming


    Not sure why CheetahMobile has 3 apps with gradually more bulk, more bugs, and a few extra features, but this is the best, most efficient, and lightest of the 3! If you have a low-end toaster which could use a complete overhaul, this is the app you need!

  46. Jon Tyler-avatar

    Did not find that it did anything to my phone. I have a booster program on my phone that I have to tap constantly to free up my phone when it slows down. I thought your program would do it automatically when the screen goes off as it said it would but does not.

    Constantly crashes. Have sent several crash logs but they apparently don't want to fix it. When it works, it's great, though if they don't fix the crashes by end of the year, I'm installing a replacement app.

  48. A Google user-avatar

    Impressive! First try of cleaning my samsung and it's obviously faster now. My sluggish phone have been disappointing me, i have uninstalled most my apps. but once i tried thiss app, i saw diffrence even with just swiping across apps. i really hope this is the answer to my "sleepy phone"

  49. Roman The Magician-avatar

    Roman The Magician


    Still one of the best! it works for my Google pixel 3xl well enough to keep it in a top shape possible. However, I'm missing the CM Battery option now because the app was discontinued recently. If added to, I'll be happy to give 5* immediately!

  50. Pinking Lily-avatar

    This is a really great app. It actually does what it says except this app is compact. Well, not anymore cause updates now makes it a 50mb+ app. Not good cause it defeat the purpose of you installing it. Now I got a 20mb update which I think will do absolutely nothing.

  51. Rex Robo-avatar

    WARNING!! This app will DELETE FILES in your Download folder. Also App wants internet access. Why is an app that claims to have "no ads" so aggressively attempting to gain internet access? 30+ attempts to access Internet in the four or five minutes it was installed. Uninstalled

  52. Levi Beck-avatar

    I think it slowed my phone, had wierd phone lag/frame freezes since installed, uninstalled it and the freezing at random stopped. I think it's a legit app, but it did me no good personally. I used a different cheeta app before and had no issues. but oh well.

  53. Divya K-avatar

    Speed booster is very helpful.lt prevent overheating of the phone.so l felt it is very useful. By, Divya.k , mudavannur ,kerala state.

  54. Peter Wexler-avatar

    So far, so good. The app has really helped my Amazon Kindle Fire's performance.

  55. Lee Schneider-avatar

    Excellent app. NO AD'S!!! NONE!!!! cleans my device in approximatley 10 -- 20 seconds, AMAZING. At no COST!!! I HIGHLY recommend this for anyone.👈😊👍

  56. Choice Johnson-avatar

    It's a nice little app to use. Definitely no ads is awesome, but it doesn't speed my devices up as fast as Clean Master does. This app is okay, though. Nice design. It stops a lot for some reason, though.

  57. GJH111 Salv-avatar

    It's quite a nice app. It really help my smartphone improve that only has 600mb of ram which makes it regularly slow and excluded from alot of other apps. But this helped alot. For it's simplex ui and uses it works surprisingly well.

  58. Yash Pawar-avatar

    Guyz i m tell that, "honestly its best application for clean our mobile 📱" after 2 months i m using this application is works so smoothly and i remember my setting thst is most best "auto clean after phone sleep" honestly in low MB consumption also its adfree so i like most app it my ram is 2GB so when my phone start lagging (means playing games it lag) so i clean my memory booster after cleaning my phone get boosted its very good performance while playing games.If you like my review give me 👍

  59. Christian Kane-avatar

    Beware the " shake phone to take a picture function. " finally found out why my phone was dying so quick in Hawaii, kept turning the phone on in my pocket. Many great pictures lost because of dead battery due to this app. Buh-bye

  60. Nishat Rastogi-avatar

    this app is so amazing donot need anything improve in interface and if u want to improve don't add anything please its a request i open this app and after firt look into it it is amazing. please note my feedback. this is very good and has a decent interface dont change on this and simple also

  61. Angela Amore-avatar

    this is the best app. for cleaning ur computer type unit no flaws at all. just takes getting use to the different functions. no disappointment in this app. 5 stars my friends 2bad they can't make games this way without the ads. hint hint. needs a hiberntion mode 4 batery draining apps

  62. Steven Gregory-avatar

    What a joke. Boost ur phone it shows 93 points. Wait 1 minute and do it again shows 93 points. All i found was this app heated up my CPU so fast and slowed my phone down even more. Uninstalled. Found CLEAN MASTER works much better and now my phone runs cool and quick. Avoid speed booster people.

  63. ML P-avatar

    Loooove this app! IT IS THE BEST. No Ads! The only one out there without them. Simple to use and understand. Like the power boost one touch widget as well. Freed up 8 GB on my phone. Note 5 still! 😄💖 Thank you sooo much!

    This app is without a doubt the best one I've ever had. No ads, no constant reminders to boost one thing or another. It's fast and does a great job. I just hope they don't start adding all the junk the other apps have. The 5 star rating is well deserved.

    I feel that my phone began to work, though not by much, but faster. Default system cleaner performed only a "homeopathic" function.

  66. Laurie Simpson-avatar

    I love it because it doesn't butt in my games t's very fast and simple. And best of all. It works great. With this app. I need no other booster apps. You might say it's a One Stop Shop:)

  67. Afzal Shamim-avatar

    i use my device for gaming and as my device getting old, i am starting to face lag while playing. i download this app to make my gaming experience smoother but i didn't find it very useful. i rather recommend to look for some other app.

  68. VannDigital-avatar

    This was 1 of the best damn apps I've used until my phone updated to Nougat and now Oreo. Now it has no effect as the app is always at 100% plus I no longer get the message at the bottom of my screen saying how much memory was saved on my phone.

  69. Seth Carr-avatar

    This app has boosted my phone by a LONG shot! If your phone is slow, and you want it to be faster and smoother, I definitely would recommend getting this app!

  70. Mehran Haider-avatar

    The app crashes frequently. Please fix the issue soon. I have used this app before and it used to be really great and it deserved a 5 star, not 2.

  71. Jason Greger-avatar

    I have seen so many apps like this that made similar claims, but this app is simply phenomenal! Always there to help you with issues that you may never have found on your own it definitely surpassed my expectations...

  72. J.D. Wentzel-avatar

    Closed all apps, then ran app supposedly it deleted 1.2 GB of junk launched game, it started looking up. Closed game reran this app it says deleted .98 gb. My phone before all of this had 3.7 of the usable space used this app does not free up space like it says still same with this app

  73. Kelsey Volner-avatar

    I love this booster app! Every time I get a new device, this is literally the first app that I install. It always works great, really helps with device speed, and has zero ads! I also really like the 1 tap boost widget/icon.

  74. J. M.-avatar

    I love the feature that frees up RAM after I wake the phone, and the new ability to shake the phone to launch the camera is awesome (even when the phone is off or locked).

  75. Dil Se-avatar

    Excellent app I have ever come across so for, so to say. It's amazingly user-friendly and cleans up junks etc., in a jiffy, thanks to the developer for non-inclusion of any 'ad' that gives immensely wonderful an experience...!

  76. Richard Gugula-avatar

    It makes my phone go faster and it offers an option where you can shake the phone to unlock in camera mode. Awesome idea keep up the good work!

  77. Itta Skittles-avatar

    I was recommended this app because of some viruses. So, I installed it, and it deleted three GB of junk. My device has never ran more smoothly!

  78. A Google user-avatar

    Impressive! This is a must-have mobile app to keep your device/s operating smoothly and without overheating from long duration use. Try it.

  79. Richard Allert-avatar

    It's a really good app and I have no problems with it at all! The UI is simply amazing and I'm so glad that downloaded it! Definitely worth using!

  80. Lloyd Boone-avatar

    Great App! Simple but very effective! Unlike many other apps making similar claims to free up memory and other resources, this App actually works. Well done! Thank you!

    Great application. Used it in the past and it was great. Love the fact that they're no ads. It greatly boosted and still boosts my device.

  83. A Google user-avatar

    It's the best amongst the best ,just apply the auto and the other points, it's exactly doing what it says. It just great and amazing -thanks

  84. Cultusfit-avatar

    Works good. Better than a restart for my games. But keeps putting it's app on desktop. Even when it's already there.... Ending up with 3 of same app is annoying

  85. MARISSA MERCADO-avatar



    My phone is still SLOW...I thought it will speed up , but it's not, NO GOOD Apps... Very slowly when I keep boosting it

  86. A Google user-avatar

    The first good booster app I've used that doesn't contain tons of disturbing adds, also very light, useful and easy to use. 100% would recommend.

  87. Ray Thomas-avatar

    I seldom give rating to any apps actualy, this apps REALLY! helps my note 2 N7100 alots! Because i always need doin to clear some ram in the background manually but this apps doin it good and auto kill the ram save me times!

  88. Kazuma Sato-avatar

    easy to use doing every thing with one touch real not fake and low space for low end mobiles

  89. Fun Booster-avatar

    I think it deserves 6 star but there,s no option like that.. jokes apart. That the first app that works really.. in my mobile.

  90. Jay W-avatar

    Really solved a lot of my phone speed problems! Didn't realise how much junk i actually had sitting on my phone. Thanks so much! 5 stars!

  91. A Google user-avatar

    Finally a booster that doesn't have any ads. Very simple to use. Needs a unwanted calls section.

  92. Robert Richman-avatar

    If you have a High end phone like LGG5-7 & SAMSUNG GALAXY 6-9, IT gives you just enough cleaning to clean & boost the little extras, that waste battery & Ram. If u have a ghetto phone, this cleaner is not near enough!!! Use SECURITY 360 IN THAT CASE...👍👍🇺🇸

    This is an app that actually works. I could tell my phone works faster. A lot of them don't they just have a lot of graphics. But this thing really does work.

  94. Great tutorials-avatar

    Great tutorials

    Update: last update is now stable and I can use it again, thanks 😃😃. After last update, can not clear my rRAM and every time I try it, ur app closed, I really love to use ur app, but with this issue, ur app become useless for me.

  96. A Google user-avatar

    Very easy and excellent to use! I don't have to worry anymore if the memory are full! Just only one tap and its working.

  97. Esma Talal-avatar

    I ♥ this app. It keeps my phone smooth and fast and important thing is that it's in very light weight, not heavy on phone's memory. Many good features like when we turn on the phone auto boost kills the extra cache etc. Superb ever.

  98. Bill Johnson-avatar

    Perfect. Quick boost app....no ads EVER and even have a quick shortcut icon the clean up memory with a touch, don't even have to open main program.....exactly what I was looking for...guys did a great job making and designing this app!

  99. Josh Wright-avatar

    seems to work good and cleans alot only thing i would add is if you added a way to permanently move apps to sd card every time I try it on my phone it somehow changes back to being stored on phone memory after I move the app to sd card.

  100. Aim Ami-avatar

    Its not clean my ram anymore. After i use this app, my recent apps still runing in background. When i open my app, it still show my latest page before i use booster. So i think this app not boost my phone. Also when i reopen this app after 3 hours, it show i have clean my ram. But i just open the app, when i clean my ram?
